Abstract: In this work investigations on the afterheat removal concept of the high temperature pebble bed reactor HTR-500 are made. Besides the afterheat removal the operation of circulators in special loops and coolers the afterheat removal by natural convection is part of the concept. lt is therefore of special interest to investigate the assumption, that the cooling gas flows downwards in the pebble bed. The main investigation points are : 1) How is it possible to reach for every possible accidentvariant the starting conditions for the downwards flow in the pebble bed? 2) Under which conditions an inversion of the flow may appear? 3) Which assumptions have to be fulfilled regarding the reactor so that an afterheat removal with opposite flow can be done without damage? The necessary simulation calculations (to point 2 and 3) are performed with a modified version of the Jülich plant simulation programme THERMIX.
